The emerald ash borer (EAB) is an invasive beetle species that has been reported from several central and mid-western states in the U.S. EAB impacts all species of North American ash trees, and has caused several million dollars (U.S.) in damage to trees across the affected region. This project is assessing the potential risk of EAB introduction in the mid-Atlantic region of the U.S., where the species has not yet been as widely reported.
